adjustable width frame?

Does any one know if there is a cat frame out there that has an adjustable width? I just bought a 12' cat for a low water gear boat and want to be able to adjust it between a 4 foot width and 6 foot width depending on the water level and river I'm running, but I don't want to have to built or buy two frames.

even if you could adjust it easily then you would need two sets of oars (not cheap). my suggestion is to just stick with one width that is dialed in for what you do most and learn to compensate for the other situations with what you have.

Hi,

You can achieve something akin to this by rigging a cat frame using the NRS "Retro" downbars. They can be moved in and out on the upper frame crosstubes, to give you some adjustability for tube width.

There are some limits to how far in and out you can go. But I've got one like this that is reasonably flexible -- it can provide as much as 72" equivalent width, and it goes down to about 60" width as well. The limiting factor is how much you will tolerate the top portion of the frame being off-center. IIRC, my basic width is 66", which allows me to go about 6" each way. But I use it with 16'/25" NRS tubes, so they allow a bit more off-center than smaller diameter tubes would.

FWIW.

Different sets of oars are not a problem. I have 6, 8, 10, and 12 footers. The idea of just moving the downbars is an interesting idea. It sounds like to know commercially makes one, is this true?

Hi,

Take a look at these, which will convert any standard NRS-type frame to a cat frame.

NRS Frame Drop Side Rails

Hope this helps.
